03-07 Truck Electronic Throttlebody Hellcat Adapter

This adapter harness is designed to connect a Hellcat throttle body to 2002–2007 GM truck electronic throttle control systems. The harness is fully plug-and-play and only requires connection to a 12V ignition power source. It is intended for use with single 8-pin electronic throttle wiring harnesses and adapts them to the 6-pin Hellcat throttle body.

All OEM GM LS drive-by-wire (DBW) control systems can support operation of a Hellcat throttle body. Most applications only require replacement of the throttle body connector with the Hellcat-style connector. Systems using 8-pin DBW throttle bodies, as well as certain 6-pin silver-blade throttle bodies, utilize different electrical signaling and will require additional electronic adaptation.

⚠️ Vehicle and ECU compatibility should be verified before installation.
